oh my god it works! guys it actually works!
all right we're going to attempt to build a real-life lightsaber
we've received numerous requests and we're finally taking this project on now
the funny thing is with lightsabers everyone's all so focused on making a
lightsaber aspect but no one really pays attention to the power supply because
the truth of the matter is how are you going to get that much power into something that'll
actually allow you to cut through things it's just like Tony Stark's arc reactor
even if we could build a fully functional Iron Man suit or in this case
a lightsaber we'd have no way of powering it in a compact small way but
that's never stopped us before!
all right so how are we going to do it? now getting the power isn't actually an
issue we've got tons of these zippy batteries from hobbyking but how are we
going to fit it into the lightsaber hilt? now luckily in some Star Wars comics
there's actually a concept called a protosaber, quite literally a prototype
lightsaber and guess what it features a battery backpack so that's exactly what
we're going to do! Now the tricky part is with that many batteries how are you
going to turn the power on we can't just use a regular light switch...
As you can see you can't just use a regular light switch and that's where Digikey
comes into play, you see they're actually sponsoring this project and providing us
with some rather specialized components for us to build our very own lightsaber power supply.
Alright so how does it work
We're using a whole bunch of MOSFETs in parallel to turn the power supply on and
off for more information about how the circuit works click the link in the
description below
all right so we've got the power control unit all done and for the first test we
actually live streamed it to our vlog channel so if you guys haven't
subscribed to that channel yet, you probably should otherwise you're going
to miss out on future epic live streams where we test our gadgets for the very
first time, so you really want to make sure you subscribe to that channel anyways
this is what happened.
Alright guys this may be the last
video the Hacksmith channel ever releases because we are about to test our
lightsaber power supply which consists of 20 lithium polymer batteries producing
over 200 kilowatts of power that is more electricity than three North American
homes can produce and if something goes wrong the whole thing goes boom.
On the Hacksmith channel where safety is number one priority
all right three... oh god... back up... two... one -- I didn't like that beep oh holy crap look at that
that is red-hot steel ohhh... like it oh my god it works
GUYS, GUYS, IT ACTUALLY WORKS! I was, I was somewhat skeptical but it is working!
Okay, now we only have two rods which means they will heat up a lot faster....
it's gotten so hot little bits of metal are flying off the steel look at
that there's a little molten blobs of metal
that solid steel that's ridiculous! Can we like hit it with something?
Oh, there it goes...
Alright so that went pretty good but we made a couple changes
and tried it again and then something bad happened
SMOOOOKINNNN
all right so what the heck happened there? Uhh one of the components actually
caught fire probably because we're overloading the circuit a little bit and
we used a chemical fire extinguisher to put it out because we didn't want the
fire to spread to the batteries unfortunately a chemical fire
extinguishers make really nasty kind of yellow smoke and some passerby or maybe
a neighbor saw smoke coming out of our garage so they called 9-1-1 and a Police
Cruiser showed up and I think three fire trucks luckily after they saw that we
didn't actually have a real fire it was just a fire extinguisher they left but
we learned a big lesson and that is we need more safety factors in our designs
we're actually completely redesigning power supply and beefing it up like
crazy so this doesn't happen again that power supply is going to give us enough
electricity or the lights hit but how do you think we're actually going to make
the saber part of it let us know in the comments below and suggest some things
for us to cut through thanks for watching
